Description
Technical field
A kind of Tunnel Blasting mark eye chi of the utility model, belongs to Tunnel Blasting mark eye technical field of tools.
Background technology
Explosion is the main method that stone matter surrounding rock tunnel excavates, and has main steps that, is first being opened using air pressure gun or rock drill
Dig region and set explosion eye, be then charged into the blasted materials such as emulsion, pass through shock wave caused by explosive blasting and stress wave
Producing huge acting ability to country rock around makes stone matter rock crusher, and so as to reach the effect of excavation, Tunnel Blasting eye is really
It is fixed to turn into the deciding factor for influenceing Blasting Excavation.The sign of conventional tunnel explosion eye estimates or used chi mainly by operating personnel
Son measures, and is then indicated, not only low the effect of sign, and accuracy in measurement is inaccurate, causes tunnel to backbreak or owe to dig,
Construction quality is not only have impact on, and adds the workload of workmen, causes a certain degree of waste of material.
Row those skilled in the art know altogether, and during tunnel blasting excavation, the sign of explosion eye is the crucial ring of blast working
Section, explosion eye is accurately indicated, the precision and line style of tunnel blasting excavation can be effectively controlled, reduce the nothing to tunnel surrounding
Sequence disturbs, and protects the force structure of country rock, is advantageous to the lifting of Inspection of Tunnel Quality；Tunnel can be effectively controlled to backbreak, owe simultaneously
The threshold value of digging, the workload of workmen is reduced, reduce the waste of material.But so crucial technology, all the time
All completed by workmen's ruler amount or estimation, random big, low precision, operating efficiency is low.
Utility model content
The utility model overcomes the shortcomings of the prior art, there is provided a kind of Tunnel Blasting mark eye chi, is exclusively used in tunnel
The sign of road explosion eye, there is the advantages of sign precision is high, and the used time is few, effect is high.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of Tunnel Blasting mark eye chi, bag
Protractor, flexible Sopwith staff, base, rotary shaft and screens device are included, the protractor is fixedly installed on base, the flexible Sopwith staff
Lower end protractor bottom is hinged on by rotary shaft, the screens device is movably arranged on the arc-shaped side of protractor along upper, is used for
Fixed flexible Sopwith staff, the flexible Sopwith staff both sides inside are equipped with iron bar, and the iron bar is used for the magnet intraoral with being arranged on mark eye
Absorption, flexible Sopwith staff is positioned on mark eye mouth.
The protractor radius is 0.4~0.6m, and material is aluminium-plastic panel.
The elongation range of the flexible Sopwith staff is 1~8m.
The utility model has an advantageous effect in that compared with prior art：The utility model Tunnel Blasting mark eye chi, behaviour
Make that simple, mark eye is accurate, work efficiency is high, it is low or the defects of inaccurately bring effectively to solve conventional art acceptance of the bid eye efficiency, has
The out break in the control tunnel of effect, it is ensured that constructing tunnel quality, while avoid the waste of material.
Brief description of the drawings
The utility model is described further below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure：1 it is protractor, 2 be flexible Sopwith staff, 3 be mark eye mouth, 4 be base, 5 be rotary shaft, 6 is screens device.
Embodiment
As shown in figure 1, a kind of Tunnel Blasting mark eye chi of the utility model, including protractor 1, flexible Sopwith staff 2, base 4, rotation
Rotating shaft 5 and screens device 6, the protractor 1 are fixedly installed on base 4, and the lower end of the flexible Sopwith staff 2 is cut with scissors by rotary shaft 5
It is connected on the bottom of protractor 1, the screens device 6 is movably arranged on the arc-shaped side of protractor 1 along upper, for fixed flexible Sopwith staff 2, institute
State and iron bar is housed inside the flexible both sides of Sopwith staff 2, the iron bar is used for the magnet adsorption with being arranged in mark eye mouth 3, by telescopic tower
Chi 2 is positioned on mark eye mouth 3.
The radius of protractor 1 is 0.4~0.6m, and material is aluminium-plastic panel.
The elongation range of the flexible Sopwith staff 2 is 1~8m.
Screens device 6 is consistent with the camber line of protractor 1 in the utility model and is fitted with screens screw, for fixing telescopic tower
Chi 2, and the flexible inside of Sopwith staff 2, equipped with the iron bar to match with Sopwith staff size, mark eye mouth 3 is by iron sheet box and mark eye reinforcing bar group
Into iron sheet cassette interior is equipped with NdFeB rear-earth magnet.Marking eye mouth 3 can be by the magnet adsorption in iron sheet box in equipped with iron
On the flexible Sopwith staff 2 of bar.Its eye mouth base of getting the bid is the rectangular box made of iron sheet, and size is 5cm*2cm * 1cm, built-in chi
The very little NdFeB rear-earth magnet matched with iron sheet box, can quickly be adsorbed on flexible Sopwith staff.
The arch steel that the utility model acceptance of the bid eye reinforcing bar is diameter 5cm.
Protractor 1 and flexible Sopwith staff 2 be with the use of forming two-dimensional coordinate system in the utility model, by its it is parallel press close to tunnel
Face, it can accurately find tunnel tunnel face explosion eye.
The utility model acceptance of the bid eye mouth 3 can be easily installed on flexible Sopwith staff 2, so as to complete to the accurate of explosion eye
Sign.
Screens device 6 can fix flexible Sopwith staff 2 after flexible Sopwith staff 2 determines explosion eye in the utility model, convenient working
Personnel enter rower eye.
Embodiment of the present utility model is explained in detail above in conjunction with accompanying drawing, but the utility model is not limited to
Embodiment is stated, in those of ordinary skill in the art's possessed knowledge, the utility model aims can also not departed from
On the premise of various changes can be made.
